下文描述通常係關於無線通信，且更具體言之，係關於在無線通信環境中之有效鏈路指定。The following description is generally related to wireless communications and, more specifically, to efficient link assignments in a wireless communication environment.
無線通信系統業已變成一種流行的通信方式，全世界很多人藉由該方式進行通信。為了滿足消費者需要且改良攜帶性及便利性，無線通信器件業已變得更小且功能更強。行動器件(諸如，蜂巢式電話)的處理功率之增大使得對無線網路傳輸系統之需求提高。該等系統通常不如在該處通信之蜂巢式器件那麼容易更新。當行動器件性能擴展時，很難以便於充分利用新的及改良的無線器件性能之方式維持較舊的無線網路系統。Wireless communication systems have become a popular form of communication, and many people around the world communicate by this means. In order to meet consumer needs and improve portability and convenience, wireless communication devices have become smaller and more powerful. The increased processing power of mobile devices, such as cellular phones, has increased the demand for wireless network transmission systems. These systems are generally not as easy to update as the cellular devices that communicate there. As mobile device performance expands, it is difficult to maintain older wireless network systems in a way that takes advantage of new and improved wireless device performance.
更特定言之，基於分頻之技術通常藉由將頻譜分成均一頻寬塊而將頻譜分成不同的通道，例如，配置用於無線通信的頻帶之劃分可分成30個通道，每一通道可載運音訊交談內容，或(為數位服務)載運數位資料。每一通道每次僅可指定至一使用者。一已知變化係正交分頻技術，其有效地將整個系統頻寬分成多個正交子頻帶。該等子頻帶亦稱作音調、載波、副載波、區間，及/或頻率通道。每一子頻帶與可用資料調變之副載波相關聯。對於基於分時之技術，頻帶在時間方面分成連續時間片(time slice)或時槽。每一通道使用者具備以循環方式傳輸及接收資訊之時間片。舉例而言，在任一指定時間t，在短叢發內向使用者提供至通道之存取。接著，存取切換至另一使用者，另一使用者具備用於傳輸及接收資訊之短叢發時間。"依次"之循環繼續，且最終每一使用者具備多個傳輸及接收叢發。More specifically, the frequency division based technique generally divides the spectrum into different channels by dividing the spectrum into uniform bandwidth blocks. For example, the frequency band configured for wireless communication can be divided into 30 channels, each of which can be carried. The content of the audio conversation, or (for digital services) carrying digital data. Each channel can only be assigned to one user at a time. A known variation is an orthogonal frequency division technique that effectively divides the overall system bandwidth into multiple orthogonal sub-bands. These sub-bands are also referred to as tones, carriers, subcarriers, intervals, and/or frequency channels. Each subband is associated with a subcarrier that can be modulated by the data. For time-based techniques, the frequency band is divided in time into a continuous time slice or time slot. Each channel user has a time slice that transmits and receives information in a round-robin fashion. For example, at any given time t, access to the channel is provided to the user within the short burst. Then, the access is switched to another user, and the other user has a short burst time for transmitting and receiving information. The "sequential" loop continues, and eventually each user has multiple transmission and reception bursts.
基於分碼之技術通常在一定範圍內、在任一時間，在諸多可用頻率上傳輸資料。一般而言，資料可經數位化且在可用頻寬上展頻，其中多個使用者可在通道上被覆蓋，且可指定唯一序列碼給個別使用者。使用者可在相同的寬頻帶頻譜塊中傳輸，其中每一使用者之訊號在整個頻寬上由其個別唯一展頻碼展頻。該技術可提供來用於共用，其中一或多個使用者可同時傳輸及接收。該共用經由展頻數位調變可達成，其中使用者之位元流經編碼且在極寬通道上以偽隨機方式展頻。為了以一致方式收集用於特定使用者之位元，接收器經設計以認出相關聯唯一序列碼且取消隨機化。Fragment-based techniques typically transmit data over a range of available frequencies, at any time, within a certain range. In general, data can be digitized and spread over the available bandwidth, where multiple users can be overlaid on the channel and a unique sequence code can be assigned to individual users. The user can transmit in the same wide-band spectrum block, where each user's signal is spread over its entire bandwidth by its individual unique spreading code. This technique can be provided for sharing, where one or more users can transmit and receive simultaneously. This sharing can be achieved via spread spectrum digit modulation, where the user's bits are encoded and spread over a very wide channel in a pseudo-random manner. In order to collect bits for a particular user in a consistent manner, the receiver is designed to recognize the associated unique sequence code and cancel the randomization.
典型無線通信網路(例如，使用分頻、分時及分碼技術)包括一或多個基地台，其提供覆蓋區域及可在覆蓋區域內傳輸及接收資料之一或多個行動(例如，無線)終端機。典型基地台可同時傳輸用於廣播、多點播送及/或單點播送服務之多個資料流，其中資料流為對行動終端機而言具有獨立接收興趣之資料流。在該基地台之覆蓋區域內之行動終端機對接收由複合流載運之一個、一個以上或全部資料流感興趣。同樣的，行動終端機可將資料傳輸至基地台或另一行動終端機。基地台與行動終端機之間或各行動終端機之間的該通信可歸因於通道變化及/或干擾功率變化而降級。A typical wireless communication network (eg, using frequency division, time division, and code division techniques) includes one or more base stations that provide coverage areas and one or more actions that can transmit and receive data within the coverage area (eg, Wireless) terminal. A typical base station can simultaneously transmit multiple data streams for broadcast, multicast, and/or unicast services, where the data stream is a stream of data that has an independent reception interest for the mobile terminal. The mobile terminal within the coverage area of the base station is interested in receiving one, more than one, or all of the data streams carried by the composite stream. Similarly, the mobile terminal can transmit data to the base station or another mobile terminal. This communication between the base station and the mobile terminal or between the mobile terminals can be degraded due to channel variations and/or interference power variations.
此外，對於使用固著指定(例如，其中保留指定直至解除指定)之系統，可靠傳遞鏈路指定訊息係重要的，否則接收器不知道哪一個通道解調變，且因此不能將其預期封包解碼。系統通常使用指定認可訊息來確認指定訊息之接收/未接收。然而，發送該等指定認可訊息既浪費時間亦浪費能量，且通常不完全可靠。其他系統使用非固著指定，其中指定之頻繁終止提供保護以防偶爾出現之指定誤差。然而，在諸多情況下，不使用固著指定可能不可行。In addition, for systems that use stipulation designation (for example, where the designation is reserved until de-assignment), it is important to reliably pass the link designation message, otherwise the receiver does not know which channel is demodulated and therefore cannot decode its expected packet. . The system usually uses the specified approval message to confirm the receipt/non-receipt of the specified message. However, sending such designated accreditation messages wastes both time and energy and is generally not completely reliable. Other systems use non-fixed designation, where the specified frequent termination provides protection against occasional specified errors. However, in many cases, not using a fixation design may not be feasible.
因此，為了改良系統通量且增加使用者經驗，在該項技術中有必要存在便利有效排程之系統及方法。Therefore, in order to improve system throughput and increase user experience, there is a need in the art for systems and methods that facilitate efficient scheduling.
為了基本瞭解一或多個實施例，下文呈現該等實施例之簡單概要。該概要不是所有所涵蓋實施例之泛泛的綜述，且希望既不識別所有實施例之主要或關鍵元件，亦不描述任意或所有實施例之範疇。其唯一的目的為，以簡化形式呈現一或多個實施例之一些理念，以作為下文呈現的更詳細內容之序文。For a basic understanding of one or more embodiments, a brief summary of the embodiments is presented below. This Summary is not an extensive overview of the various embodiments, and it is intended to neither identify the essential or critical elements of the embodiments or the scope of any or all embodiments. The sole purpose is to present some concepts of the embodiments of the invention
本發明係關於，當存取節點("AN")未將指定解碼時，藉由提供指定之立即重新發送而便利通信之系統及方法。一般而言，若在反向鏈路上發送指定，其中"AN"將指定成功地解碼，則該解碼可作為認可訊號("ACK"，例如，指定認可訊號)。此外，未能解碼指定通常不明確指示是解碼已丟失還是存取終端機(AT)已丟失指定；且因此本發明之一實施例提供立即重新發送指定。該方式降低對AT指示"是"(表示接收到指定)或"否"(表示未接收到指定)之需求。因此，若AN未解碼指定，則重新發送該指定，(例如，一旦AN未能將指定解碼，則立即重新發送指定)，且可接著移除請求等待時間。The present invention relates to systems and methods for facilitating communication by providing a designated instant retransmission when an access node ("AN") does not specify a decoding. In general, if the designation is sent on the reverse link, where "AN" will specify successful decoding, then the decoding can be used as an acknowledgement signal ("ACK", for example, to specify an acknowledgement signal). Furthermore, failure to decode specifies that the usually unclear indication is whether the decoding has been lost or that the access terminal (AT) has lost the designation; and thus one embodiment of the present invention provides an immediate retransmission designation. This mode reduces the need for the AT to indicate "Yes" (indicating that the designation was received) or "No" (indicating that the designation was not received). Thus, if the AN does not decode the designation, the designation is resent (eg, once the AN fails to decode the designation, the designation is resent immediately) and the request latency can then be removed.
在相關實施例中，回應於AT之請求訊息(說明待發送之資料量)及所需之服務品質(例如，用於在網路中工作之反向鏈路排程器)，AN可接著提供指定至反向鏈路。當未接收到封包時，系統假設請求仍有效(例如，儘管未接收到封包，仍驗證請求)，且在未被要求新請求下立即發送新指定。因此，藉由重新指定完全相同之指定，降低對"AT"發送另一請求之需求。同時，在反向鏈路上，封包之適當"AN"解碼可作為表示準確接收該指定之驗證，在該情況下，若其丟失對該指定之解碼，則不再需要重新發送指定。In a related embodiment, in response to the AT's request message (declaring the amount of data to be sent) and the required quality of service (eg, a reverse link scheduler for operation in the network), the AN may then provide Assigned to the reverse link. When no packet is received, the system assumes that the request is still valid (eg, the request is verified even though the packet was not received) and immediately sends the new designation without requesting a new request. Therefore, by reassigning the exact same designation, the need to send another request to "AT" is reduced. At the same time, on the reverse link, the appropriate "AN" decoding of the packet can be used as a verification to accurately receive the designation, in which case the re-send specification is no longer needed if it loses the decoding of the designation.
根據另一實施例，在"ACK"(例如，認可訊號)不需在前向鏈路上發送以支援反向鏈路訊務之系統中，本發明便利一維護用於反向鏈路指定之媒體存取控制(MAC)邏輯之機制。在相關實施例中，當AT請求指定以傳輸資料，且AN接著將指定發回時(其尚未接收待解碼之相關聯封包)，則本發明可對指定重新發送之次數設限。因此，一旦達到重新發送嘗試之預定次數，便可選擇另一資源。此外，解除指定訊息亦可發送至AT以終止指定請求。According to another embodiment, the present invention facilitates maintaining a medium for reverse link designation in a system where "ACK" (eg, an acknowledgement signal) does not need to be sent on the forward link to support reverse link traffic. The mechanism of access control (MAC) logic. In a related embodiment, the present invention may limit the number of times a resend is specified when the AT request specifies to transmit the data and the AN then sends the design back (which has not received the associated packet to be decoded). Therefore, once the predetermined number of resend attempts is reached, another resource can be selected. In addition, the unsubscribe message can also be sent to the AT to terminate the specified request.
在相關實施例中，本發明通常不需要針對固著指定之指定認可訊息，其中該等訊息使用寶貴資源。舉例而言，在RL中，若AN將封包解碼，則在無指定認可訊息輔助情況下，其認識到行動單元(例如，使用者器件)業已接收到指定。或者，若AN未能將無效指定之封包解碼，則其重新發送指定訊息。若該行動單元確實丟失指定，則AN通常確實需要重新發送指定訊息，且因此該傳輸不是額外負擔，且不消耗額外資源。同樣的，若AN歸因於劣質通道而丟失解碼，則重新發送指定訊息可作為讓行動單元重新傳輸封包之指示。類似的，若AN歸因於丟失封包開始(SOP)而丟失解碼，則重新發送指定訊息讓AN與行動單元重新同步。此外，執行各種操作/方法之構件可以軟體/硬體組件形式提供以執行本發明之態樣。In a related embodiment, the present invention generally does not require an approved message for the fixation specified, wherein the message uses valuable resources. For example, in the RL, if the AN decodes the packet, it recognizes that the mobile unit (eg, the user device) has received the designation without the aid of the designated acknowledgement message. Or, if the AN fails to decode the invalid designated packet, it resends the specified message. If the mobile unit does lose the designation, the AN typically does need to resend the specified message, and therefore the transmission is not an additional burden and does not consume additional resources. Similarly, if the AN loses decoding due to a poor channel, resending the specified message can be used as an indication to have the mobile unit retransmit the packet. Similarly, if the AN loses decoding due to a Lost Packet Start (SOP), the specified message is resent for the AN to resynchronize with the mobile unit. In addition, components that perform various operations/methods may be provided in the form of a software/hardware assembly to perform the aspects of the present invention.

首先參看圖1，說明例示性訊息交換機制100(例如，在反向鏈路上)，當指定未由"AN"(例如，接收器節點)解碼時，該機制藉由提供該指定之立即重新發送而便利通信。一般而言，若在反向鏈路上，發送指定，其中"AN"將指定成功地解碼，則該解碼可作為認可訊號("ACK"，例如，指定認可)。此外，不能將指定解碼通常不明確指示是解碼已丟失還是存取終端機(AT)丟失指定，且因此本發明之一實施例提供立即重新發送指定。該方式降低對AT指示"是"(表示接收到指定)或"否"(表示未接收到指定)之需求。因此，若AN未將指定解碼，則重新發送該指定，且可因此移除請求等待時間。Referring first to Figure 1, an exemplary message exchange mechanism 100 (e.g., on the reverse link) is illustrated. When a designation is not decoded by an "AN" (e.g., a receiver node), the mechanism resends immediately by providing the designation. And convenient communication. In general, if on the reverse link, the designation is sent, where "AN" will specify successful decoding, then the decoding can be used as an acknowledgement signal ("ACK", for example, to specify an endorsement). Moreover, the specified decoding cannot usually be ambiguously indicating whether the decoding has been lost or the access terminal (AT) loss designation, and thus an embodiment of the present invention provides an immediate retransmission designation. This mode reduces the need for the AT to indicate "Yes" (indicating that the designation was received) or "No" (indicating that the designation was not received). Therefore, if the AN does not decode the designation, the designation is resent and the request latency can be removed accordingly.
訊息交換機制100係關於自接收器節點(例如，存取節點)及發送器節點(例如，存取終端機)之傳輸。在一特定實施例中，在110處及時槽1中，發送器節點可將請求傳輸至接收器節點。接收器節點在時槽2中及112處提供授權給發送器節點。該授權可指定包括(例如)指定功率及/或指定通道(例如，通道識別(ID))之通道資源。通道可為頻帶(例如，可用頻帶之一些副載波)、時槽(例如，訊務槽之一些子槽)、展頻碼指定、其組合，或其類似物。此外，授權可額外地或替代地包括與混合自動重複請求(HARQ)相關聯之資訊。舉例而言，授權可包括HARQ片斷號、資料(例如，位元，……)，其指示傳輸器是否應傳輸新封包、舊封包之HARQ重新傳輸及其類似物。The message exchange mechanism 100 is related to the transmission from a receiver node (e.g., an access node) and a sender node (e.g., an access terminal). In a particular embodiment, at time 110 in slot 1, the sender node can transmit the request to the receiver node. The receiver node provides authorization to the sender node in time slot 2 and at 112. The authorization may specify channel resources including, for example, specified power and/or designated channels (eg, channel identification (ID)). The channel can be a frequency band (eg, some subcarriers of the available frequency band), a time slot (eg, some sub-slots of the traffic slot), a spreading code designation, a combination thereof, or the like. Further, the authorization may additionally or alternatively include information associated with hybrid automatic repeat request (HARQ). For example, the authorization may include a HARQ fragment number, data (eg, a bit, ...) indicating whether the transmitter should transmit a new packet, a HARQ retransmission of an old packet, and the like.
其次，在114處，在時槽3中，發送器節點可藉由使用指定功率及/或指定通道而傳輸導頻訊號。舉例而言，基於時槽3中自發送器節點獲取之導頻訊號及時槽3中由同時傳輸導頻訊號之不同節點造成之額外干擾，接收器節點可進一步分析訊息。Next, at 114, in time slot 3, the transmitter node can transmit the pilot signal by using the specified power and/or the designated channel. For example, based on the pilot signals acquired from the transmitter node in the time slot 3 and the additional interference caused by the different nodes transmitting the pilot signals in the slot 3, the receiver node can further analyze the message.
在116處及時槽4中，速率指定可自接收器節點傳輸至發送器節點。該速率指定係關於調變格式、編碼格式及其類似物。發送器節點可使用在時槽2中獲取的授權中指定之功率及/或通道及在時槽4中提供的速率指定中指定之速率，以隨後將資料傳輸至接收器節點。應瞭解，任意數目額外節點對可同時使用訊息交換機制100。舉例而言，訊息交換機制100能在任意數目節點對之間提供同步傳輸。In time slot 116 at 116, the rate designation can be transmitted from the receiver node to the sender node. This rate specification is related to modulation formats, encoding formats, and the like. The sender node may use the power and/or channel specified in the grant acquired in time slot 2 and the rate specified in the rate specification provided in time slot 4 to subsequently transmit the data to the receiver node. It should be appreciated that any number of additional node pairs can use the message exchange 100 at the same time. For example, the message exchange mechanism 100 can provide synchronous transmission between any number of node pairs.
因此，回應於AT之請求訊息，其說明待發送之資料量及所需之服務品質(例如，用於在網路中工作之反向鏈路排程器)，AN可獲取至反向鏈路之指定，且當未接收到封包時，系統假設請求仍有效(即使未接收到封包)，且在未被要求新請求下立即發送新指定。因此，藉由重新指定相同指定，降低對"AT"發送另一請求之需求。同時，在反向鏈路上，封包之適當"AN"解碼可指示準確接收指定之驗證，在該情況下，若對該指定之解碼丟失，則不再需要重新發送指定。Therefore, in response to the request message of the AT, which indicates the amount of data to be sent and the quality of service required (for example, a reverse link scheduler for working in the network), the AN can obtain the reverse link. As specified, and when no packet is received, the system assumes that the request is still valid (even if the packet was not received) and immediately sends the new designation without requesting a new request. Therefore, by reassigning the same designation, the need to send another request to "AT" is reduced. At the same time, on the reverse link, proper "AN" decoding of the packet may indicate that the specified authentication is received accurately, in which case the re-send specification is no longer needed if the specified decoding is lost.
圖2說明在反向鏈路中之排程器，其根據本發明之特定實施例而經由指定組件212實施指定之立即重新發送。反向鏈路排程器組件210可操作以耦接至每一無線網路204及使用者器件206。無線網路204可包含一或多個基地台、收發器及其類似物，其傳輸通信訊號並自一或多個使用者器件206接收通信訊號。此外，連同OFDM協定、OFDMA協定、CDMA協定、TDMA協定、其組合，或任一其他適當之無線通信協定，無線網路204可將通信服務提供給使用者器件206。使用者器件206可為(例如)蜂巢式電話、智慧電話、PDA、膝上型電腦、無線PC，或使用者可與無線網路204通信之任一其他適當通信器件。2 illustrates a scheduler in a reverse link that implements a specified immediate retransmission via designated component 212 in accordance with a particular embodiment of the present invention. The reverse link scheduler component 210 is operative to couple to each of the wireless network 204 and the user device 206. Wireless network 204 can include one or more base stations, transceivers, and the like that transmit communication signals and receive communication signals from one or more user devices 206. Moreover, wireless network 204 can provide communication services to user device 206 in conjunction with an OFDM protocol, an OFDMA protocol, a CDMA protocol, a TDMA protocol, a combination thereof, or any other suitable wireless communication protocol. User device 206 can be, for example, a cellular telephone, a smart phone, a PDA, a laptop, a wireless PC, or any other suitable communication device that a user can communicate with wireless network 204.
反向鏈路排程器組件210可為基於封包之排程器，且可實施鏈路指定以便利至一或多個使用者器件206之鏈路指定(例如，如上文關於圖1列出之內容)及/或頻率設定指定。舉例而言，回應於AT之請求訊息，其說明待發送之資料量且說明用於反向鏈路排程器210工作所需之服務品質，則AN可具備至反向鏈路之指定。若未接收到封包時，則系統假設請求仍有效(即使尚未接收到封包)，且在未被要求新請求下立即發送新指定。因此，藉由重新指定相同指定，可降低對"AT"發送另一請求之需求。同時，在反向鏈路上，封包之適當"AN"解碼可表示為準確接收指定之驗證；在該情況下，若其丟失對該指定之解碼，則不再需要重新發送指定。The reverse link scheduler component 210 can be a packet-based scheduler and can implement link designation to facilitate link assignment to one or more user devices 206 (eg, as listed above with respect to FIG. 1) Content) and / or frequency setting designation. For example, in response to the request message of the AT, which indicates the amount of data to be transmitted and indicates the quality of service required for the operation of the reverse link scheduler 210, the AN may have the designation to the reverse link. If no packet is received, the system assumes that the request is still valid (even if the packet has not been received) and immediately sends the new designation without requesting a new request. Therefore, by reassigning the same designation, the need to send another request to "AT" can be reduced. At the same time, on the reverse link, the appropriate "AN" decoding of the packet can be indicated as accurately receiving the specified verification; in this case, if it loses the decoding of the designation, the re-send specification is no longer needed.
圖3說明相關實施例，其中一旦達到用於指定請求之預定數目嘗試，則可選擇另一資源。此外，解除指定訊息亦可發送至AT以終止指定請求。如圖3中所示，描繪一組N個系統資源區塊300(其中N為整數)，以便利瞭解在本文所呈現之各種實施例之操作方式。該等資源區塊300可表示(例如)傳輸通道、時槽、頻率、碼槽、前述項之組合，及其類似物。對該等區塊之子集之常見描述可為(例如)區塊指數列表，諸如指定至特定使用者之區塊列表。Figure 3 illustrates a related embodiment in which another resource may be selected upon reaching a predetermined number of attempts to specify a request. In addition, the unsubscribe message can also be sent to the AT to terminate the specified request. As shown in FIG. 3, a set of N system resource blocks 300 (where N is an integer) is depicted to facilitate an understanding of the manner in which the various embodiments presented herein are operational. The resource blocks 300 may represent, for example, transmission channels, time slots, frequencies, code slots, combinations of the foregoing, and the like. A common description of a subset of such blocks may be, for example, a list of block indices, such as a list of blocks assigned to a particular user.
根據實施例，一旦達到為指定請求執行之預定次數嘗試，則縮減指定(decremental assignment)可產生及/或用來便利資源區塊管理。舉例而言，縮減指定可明示或暗示。同樣的，明示縮減指定可說明一部分使用者之現有指定，其應自使用者之指定移除，而暗示縮減指定可為至另一使用者之指定，其由第一使用者遵守，且與第一使用者之指定相衝突。在後一種情況下，至第二使用者之該衝突指定訊息可由第一使用者解釋為縮減指定。此外，藉由傳輸單個指定，其同時解除指定資源或相衝突使用者且指定該等資源至預期使用者，縮減指定之使用可進一步便利容許網路減少指定訊息負擔。縮減指定訊息亦可以如下方式傳輸，即在該方式中，指定訊息可由受解除指定影響之所有當前使用者(例如，當前資源指定與由新產生之指定所指定之資源相衝突之所有使用者，及指定之所需接受者)解碼。此外，當指定訊息在可界定的相關資源子集之數目方面受限時，則歸因於至其他使用者之現有指定，縮減指定可便利減少指定限制。舉例而言，使用者指定之間的重疊可解釋為至資源的當前受讓人之暗示縮減指定，該方式便利至新預期使用者之重疊資源之重新指定。此外，縮減指定傳輸許可根據至使用者之先前指定之驗證而確認(例如，某一確認資料之接收，諸如反向鏈路上成功的封包或序列解碼之指示、前向鏈路上之認可，……)。以該方式，網路在縮減使用者之指定之前可驗證該指定。According to an embodiment, a decremental assignment may be generated and/or used to facilitate resource block management once a predetermined number of attempts to execute for a specified request are reached. For example, a reduction specification may be express or implied. Similarly, the explicit reduction designation may indicate an existing designation of a portion of the user, which shall be removed from the user's designation, and the implied designation may be a designation to another user, which is followed by the first user, and A user's designation conflicts. In the latter case, the conflict designation message to the second user can be interpreted by the first user as a reduced designation. In addition, by transmitting a single designation that simultaneously de-alers a designated resource or a conflicting user and assigns the resource to the intended user, reducing the specified usage further facilitates allowing the network to reduce the specified message burden. The reduced specified message may also be transmitted in such a manner that the specified message may be made by all current users affected by the de-assignment (eg, the current resource specifies all users that conflict with the resource specified by the newly generated designation, And specify the required recipient) to decode. In addition, when the specified message is limited in terms of the number of definable related resource subsets, the reduction designation may be convenient to reduce the specified limit due to the existing designation to other users. For example, an overlap between user assignments may be interpreted as an implied reduction to the current assignee of the resource, which facilitates reassignment of overlapping resources to the new intended user. In addition, the reduction of the specified transmission license is confirmed based on the user's previously specified verification (eg, receipt of a certain acknowledgement, such as an indication of a successful packet or sequence decoding on the reverse link, approval on the forward link, ... ). In this way, the network can verify the designation before reducing the user's designation.
圖4根據本發明之態樣說明重新發送指定之方法400。儘管在本文中例示性方法作為一系列表示各種事件及/或操作之區塊而說明及描述，但本發明不受該等區塊之所說明次序限制。舉例而言，根據本發明，除了本文所說明之次序，一些操作或事件可以不同次序發生，且/或與其他操作或事件同時發生。此外，並非需要所有說明之區塊、事件或操作來實施根據本發明之方法。此外，應瞭解，根據本發明之例示性方法及其他方法可與本文所說明及描述之方法相關聯且與未說明或描述之其他系統及裝置相關聯而實施。初始地，在410處，請求發送至存取節點(AN)。隨後，在420處，判定AN是否可將指定解碼。一般而言，若在反向鏈路上，發送指定，其中"AN"成功地將指定解碼，則該解碼可作為認可訊號("ACK"，例如，指定認可訊號)，如425處所說明。此外，未能將指定解碼，一般而言，其不明確指示是解碼已丟失還是存取終端機(AT)丟失指定；且因此本發明之一實施例在430處提供立即重新發送指定。該方式降低對於AT指示"是"(表示接收到指定)或"否"(表示未接收到指定)之需求，如440處所說明。4 illustrates a method 400 of resending a design in accordance with an aspect of the present invention. Although the illustrative methods are illustrated and described herein as a series of blocks representing various events and/or operations, the invention is not limited by the order illustrated. For example, some operations or events may occur in a different order, and/or concurrent with other operations or events, in accordance with the present disclosure. In addition, not all illustrated blocks, events, or operations are required to implement a method in accordance with the present invention. In addition, it should be appreciated that the illustrative methods and other methods in accordance with the present invention can be implemented in association with the methods illustrated and described herein and in connection with other systems and devices not illustrated or described. Initially, at 410, the request is sent to an access node (AN). Subsequently, at 420, it is determined if the AN can decode the designation. In general, if a designation is sent on the reverse link where "AN" successfully decodes the designation, then the decoding can be used as an acknowledgement signal ("ACK", for example, to specify an acknowledgement signal), as illustrated at 425. Moreover, the designation is not decoded, in general, its ambiguous indication is whether the decoding has been lost or the access terminal (AT) loss designation; and thus an embodiment of the present invention provides an immediate retransmission designation at 430. This approach reduces the need for the AT to indicate "Yes" (indicating that the designation was received) or "No" (indicating that the designation was not received), as explained at 440.
圖5根據本發明之態樣說明重新發送指定直至達到預定次數迭代之特定方法500。初始地，在510處，請求由存取節點(AN)接收。該AN可接著在520處提供指定至AT。其次，在530處，完全相同之指定可重新發送至AT。如同先前解釋之內容，方法500可消除AT指示其指定狀態之需求。在540處，判定是否業已達到預定次數(例如，M倍，其中M為整數)之指定之重新發送。若如此，則在550處停止重新發送指定。否則，方法返回至操作530，其中指定重新發送至AT。Figure 5 illustrates a particular method 500 of resending a designation until a predetermined number of iterations are completed, in accordance with an aspect of the present invention. Initially, at 510, the request is received by an access node (AN). The AN can then provide an assignment to the AT at 520. Second, at 530, the exact same designation can be resent to the AT. As previously explained, method 500 can eliminate the need for the AT to indicate its assigned state. At 540, a determination is made as to whether the specified retransmission has been reached a predetermined number of times (e.g., M times, where M is an integer). If so, the resend designation is stopped at 550. Otherwise, the method returns to operation 530 where the re-send to the AT is specified.
圖6根據本發明之態樣說明實施重新發送指定至AT之無線通信系統600。系統600可包括多個基地台610及多個終端機620，其可連同本文所說明之一或多個態樣而使用。基地台通常為與終端機通信之固定台，且亦可稱作存取點、節點B，或一些其他術語。每一基地台610提供用於特定地理區域602之通信覆蓋。術語"小區"可表示基地台及/或其覆蓋區域(取決於術語使用之背景)。為了改良系統容量，基地台覆蓋區域可分成多個較小區域(例如，三個較小區域)，意即604a、604b及604c。每一較小區域可由個別基地收發器子系統(BTS)伺服。術語"扇區"可表示BTS及其覆蓋區域(取決於術語使用之背景)。對於分扇區之小區，用於該小區的所有扇區之BTS通常共同位於用於小區之基地台中。本文所說明之傳輸技術可用於具分扇區小區之系統及具未分扇區小區之系統。對了簡化，在下文描述中，術語"基地台"一般用作伺服扇區之固定台及伺服小區之固定台。6 illustrates the implementation of resending a wireless communication system 600 designated to an AT in accordance with an aspect of the present invention. System 600 can include a plurality of base stations 610 and a plurality of terminals 620 that can be used in conjunction with one or more aspects described herein. A base station is typically a fixed station that communicates with a terminal, and may also be referred to as an access point, a Node B, or some other terminology. Each base station 610 provides communication coverage for a particular geographic area 602. The term "cell" can refer to a base station and/or its coverage area (depending on the context in which the term is used). To improve system capacity, the base station coverage area can be divided into multiple smaller areas (eg, three smaller areas), meaning 604a, 604b, and 604c. Each smaller area can be servoed by an individual base transceiver subsystem (BTS). The term "sector" may refer to a BTS and its coverage area (depending on the context in which the term is used). For a sectorized cell, the BTSs for all sectors of the cell are typically co-located in the base station for the cell. The transmission techniques described herein can be used in systems with sectorized cells and systems with undivided sectors. For simplification, in the following description, the term "base station" is generally used as a fixed station of a servo sector and a fixed station of a servo cell.
終端機620通常散佈於系統中，且每一終端機可為固定終端機或行動終端機。終端機亦可稱作行動台、使用者設備、使用者器件，或一些其他術語。終端機可為無線器件、蜂巢式電話、個人數位助理(PDA)、無線數據機卡，等等。每一終端機620可在任一特定時刻在下行鏈路及上行鏈路上與零個、一或多個基地台通信。下行鏈路(或前向鏈路)指自基地台至終端機之通信鏈路，且上行鏈路(或反向鏈路)指自終端機至基地台之通信鏈路。反向鏈路資料通信可自一存取終端機至一或多個存取點出現，其中當指定未由存取節點("AN")解碼時，藉由提供該指定之立即重新發送可便利通信。Terminals 620 are typically interspersed in the system, and each terminal can be a fixed terminal or a mobile terminal. A terminal can also be called a mobile station, a user device, a user device, or some other terminology. The terminal can be a wireless device, a cellular phone, a personal digital assistant (PDA), a wireless data card, and the like. Each terminal 620 can communicate with zero, one or more base stations on the downlink and uplink at any particular time. The downlink (or forward link) refers to the communication link from the base station to the terminal, and the uplink (or reverse link) refers to the communication link from the terminal to the base station. Reverse link data communication can occur from an access terminal to one or more access points, wherein when the designation is not decoded by the access node ("AN"), immediate retransmission by providing the designation is facilitated Communication.
如圖6中所說明，排程器組件611可操作以耦接至基地台610、終端機620及/或使用者器件。固著組件604可指定固著指定。系統600可進一步包含記憶體612及處理器614(可操作以連接至排程器組件611)，其儲存或處理關於通道滿意度演算法、度量、可用頻率組、使用者器件頻率指定及其類似物之資訊。處理器614可操作以連接至排程器組件611(及/或記憶體612)以便利分析關於滿意度度量、頻率重新使用及其類似物之資訊。應瞭解，處理器614可為下列任一處理器：專門分析及/或產生由排程器組件611接收之資訊之處理器、控制系統600之一或多個組件之處理器，及分析並產生由排程器組件611接收之資訊並控制系統600之一或多個組件之處理器。記憶體612可額外儲存與產生頻率指定、度量及其類似物相關聯之協定，使得系統600經由功率控制演算法可調整傳輸功率或更新另一排程度量。此外，應瞭解，本文所說明資料儲存器(例如，記憶體)組件可為揮發性記憶體或非揮發性記憶體，或可包括揮發性及非揮發性記憶體兩者。As illustrated in Figure 6, the scheduler assembly 611 is operative to couple to the base station 610, the terminal 620, and/or the user device. The fixation component 604 can specify a fixation designation. System 600 can further include a memory 612 and a processor 614 (operable to connect to scheduler component 611) that stores or processes information about channel satisfaction algorithms, metrics, available frequency sets, user device frequency assignments, and the like Information about things. Processor 614 is operative to connect to scheduler component 611 (and/or memory 612) to facilitate analysis of information regarding satisfaction metrics, frequency reuse, and the like. It should be appreciated that the processor 614 can be any of the following: a processor that specifically analyzes and/or generates information received by the scheduler component 611, a processor of one or more components of the control system 600, and analyzes and generates The information received by scheduler component 611 and controls the processor of one or more components of system 600. Memory 612 can additionally store agreements associated with generating frequency designations, metrics, and the like, such that system 600 can adjust the transmit power or update another rank level via a power control algorithm. In addition, it should be understood that the data storage (eg, memory) components described herein can be volatile memory or non-volatile memory, or can include both volatile and non-volatile memory.
舉例而言，非揮發性記憶體可包括唯讀記憶體(ROM)、可程式化ROM(PROM)、電子可程式化ROM(EPROM)、電子可擦可程式(EEPROM)，或快閃記憶體。揮發性記憶體可包括隨機存取記憶體(RAM)，其用作外部快取記憶體。藉由說明而非限制，RAM可按諸多形式使用，諸如同步RAM(SRAM)、動態RAM(DRAM)、同步DRAM(SDRAM)、雙資料傳輸率SDRAM(DDR SDRAM)、增強型SDRAM(ESDRAM)、同步鏈路DRAM(SLDRAM)，及直接Rambus RAM(DRRAM)。For example, non-volatile memory can include read only memory (ROM), programmable ROM (PROM), electronically programmable ROM (EPROM), electronic erasable programmable (EEPROM), or flash memory. . Volatile memory can include random access memory (RAM), which acts as external cache memory. By way of illustration and not limitation, RAM can be used in many forms, such as synchronous RAM (SRAM), dynamic RAM (DRAM), synchronous DRAM (SDRAM), dual data rate SDRAM (DDR SDRAM), enhanced SDRAM (ESDRAM), Synchronous Link DRAM (SLDRAM), and direct Rambus RAM (DRRAM).
如圖6中所說明，人工智慧(AI)組件616可操作以與排程器組件611相關聯，且可做出關於調整副載波之傳輸功率之推斷，及關於何時及是否重新發送指定(例如，當該指定未由存取節點解碼時)之推斷。如本文所用之情況，術語"推斷"通常指自如經由事件及/或資料捕獲之一組觀察來推出或推斷系統、環境及/或使用者之狀態。推斷可用來識別特定環境或操作，或可產生(例如)隨狀態變化之機率分佈。推斷可為機率，意即，基於考慮資料及事件，重要狀態上之機率分佈計算。推斷亦可指用於自一組事件及/或資料構成較高級別事件之技術。該推斷使得自一組觀測事件及/或儲存事件資料形成新事件或操作之構造、推斷事件是否高度暫態鄰近相關，及事件及資料是否來自一個或數個事件及資料源。As illustrated in Figure 6, an artificial intelligence (AI) component 616 is operable to be associated with the scheduler component 611 and can make inferences about adjusting the transmit power of the subcarriers, and as to when and whether to resend the designation (eg, Inference when the designation is not decoded by the access node. As used herein, the term "inferred" generally refers to the state of the system, environment, and/or user being derived or inferred from a group observation of events and/or data captures. Inference can be used to identify a particular environment or operation, or can generate, for example, a probability distribution as a function of state. Inference can be a probability, that is, based on consideration of data and events, the probability distribution on important states is calculated. Inference can also refer to techniques used to form higher-level events from a set of events and/or materials. The inference results in the formation of a new event or operation from a set of observed events and/or stored event data, inferring whether the event is highly transiently adjacent, and whether the event and data are from one or more events and data sources.
舉例而言，至少部分基於(例如)偵測衝突指定，AI組件616可推斷適當縮減指定接受者、是否出現重新發送指定至AT之預定次數嘗試，及其類似物。此外，AI組件616連同處理器614及/或記憶體612可判定資源區塊是否由其他使用者限制及/或佔用。此外，AI組件616可根據(例如)自一組潛在候選物選擇特定使用者器件解除指定候選物，可做出關於成本效益分析之推斷。此外，至少部分基於該等推斷，縮減組件606可將特定使用者識別成待縮減之使用者，且可確保其他使用者可觀察到相衝突指定。For example, based at least in part on, for example, detecting a conflicting designation, AI component 616 can infer that the specified recipient is appropriately reduced, whether a re-send attempt to assign to the AT occurs, and the like. In addition, AI component 616, along with processor 614 and/or memory 612, can determine whether a resource block is restricted and/or occupied by other users. Moreover, AI component 616 can make an inference about a cost benefit analysis based on, for example, selecting a particular user device to de-specify a candidate from a set of potential candidates. Moreover, based at least in part on the inference, the reduction component 606 can identify a particular user as a user to be reduced, and can ensure that other users can observe conflicting assignments.
根據另一實例，AI組件616根據本發明之態樣，對於相衝突指定訊息之傳輸，可做出關於是否完全解除指定相衝突使用者之指定至另一使用者之推斷，或可對重新發送指定之次數設限。因此，一旦達到預定次數嘗試，則可選擇另一資源。According to another example, the AI component 616 can, based on the aspect of the present invention, make an inference about whether to completely disassign the designation of the conflicting user to another user for the transmission of the conflicting specified message, or can resend The number of times specified is limited. Therefore, once a predetermined number of attempts are reached, another resource can be selected.
圖7關於本文所說明各種實施例說明隨時間而執行(諸如可使用)之一系列持久或"固著"指定700。舉例而言，第一組指定在第一時框中可傳輸至使用者1－N(其中N為整數)，且該指定可持續，直至一或多個隨後指定傳輸至一或多個個別使用者。因此，第一組N個指定足夠提供系統資源指定至所有使用者，直至該等指定之變化為吾人所需及/或必要的(例如，歸因於對副載波之期望功率需求之預測之變化)。如t3處所說明，若頻率D可用，則下一個使用者(諸如U6)可指定該頻率。因此，與當使用非固著指定相比，在網路上需要傳輸較少指定訊息。本發明通常不需要指定固著指定之認可訊息，其中該等訊息使用寶貴資源。舉例而言，在RL中，若AN將封包解碼，則其認識到行動單元(例如，使用者器件)已接收指定而無指定認可訊息之輔助。或者，若AN未能將無效指定之封包解碼，則其重新發送指定訊息。若該行動單元確實丟失指定，則事實上，AN通常確實需要重新發送指定訊息，且因此該傳輸不再是額外負擔且不消耗額外資源。同樣的，若AN歸因於劣質通道而丟失解碼，則重新發送指定訊息可用於指示行動單元重新傳輸封包。類似的，若AN歸因於丟失封包開始(SOP)而使得丟失解碼，則重新發送指定訊息使AN與行動單元重新同步。7 illustrates a series of persistent or "fixed" designations 700 performed over time (such as may be used) with respect to various embodiments illustrated herein. For example, the first set of assignments may be transmitted to the user 1-N (where N is an integer) in the first time frame, and the designation may continue until one or more subsequent designated transmissions to one or more individual uses By. Thus, the first set of N assignments is sufficient to provide system resource assignments to all users until such specified changes are required and/or necessary by us (eg, due to changes in the predicted power demand for the subcarriers) ). As explained at t3, if frequency D is available, the next user (such as U6) can specify the frequency. Therefore, fewer designated messages need to be transmitted over the network as compared to when using non-fixed designation. The present invention generally does not require the assignment of a designated approval message, which uses valuable resources. For example, in the RL, if the AN decodes the packet, it recognizes that the mobile unit (eg, the user device) has received the assistance without specifying the acknowledgement message. Or, if the AN fails to decode the invalid designated packet, it resends the specified message. If the mobile unit does lose the designation, then in fact, the AN typically does need to resend the specified message, and therefore the transmission is no longer an additional burden and does not consume additional resources. Similarly, if the AN loses decoding due to a poor quality channel, then resending the specified message can be used to instruct the mobile unit to retransmit the packet. Similarly, if the AN loses decoding due to a Lost Packet Start (SOP), the specified message is retransmitted to resynchronize the AN with the mobile unit.
此外，如圖7中所說明，若使用者需要額外資源，則可用系統資源可指定至任一使用者1－N。舉例而言，除了頻率E外，可判定在網路上通信時U5有時需要使用額外頻率。下一個指定訊息可傳輸至U5以指示，指定給U5頻率E及F。此外，連同本文詳細描述之各種實施例，當重新指定頻率至U5時，該額外指定訊息可為補充指定以降低網路資源之消耗。In addition, as illustrated in FIG. 7, if the user requires additional resources, the available system resources can be assigned to any user 1-N. For example, in addition to the frequency E, it can be determined that U5 sometimes needs to use additional frequencies when communicating over the network. The next specified message can be transmitted to U5 to indicate that it is assigned to U5 frequencies E and F. Moreover, in conjunction with various embodiments described in detail herein, when the frequency is reassigned to U5, the additional designation message can be a supplemental designation to reduce the consumption of network resources.
圖8根據本發明之態樣說明特定方法800，其中解除指定訊息發送至AT以終止指定請求。初始地，在810處，由存取節點(AN)接收請求。在820處，該AN可接著提供指定至AT。隨後，在830處，實質上完全相同指定可重新發送至AT。該方式降低對AT指示"是"(表示接收到指定)或"否"(表示未接收到指定)之需求。在840處，解除指定訊息可提供來請求終止重新發送訊息至AT。同樣的，在850處，重新發送指定可停止。8 illustrates a particular method 800 in which a de-assertion message is sent to an AT to terminate a specified request, in accordance with an aspect of the present invention. Initially, at 810, the request is received by an access node (AN). At 820, the AN can then provide an assignment to the AT. Subsequently, at 830, substantially identical assignments can be resent to the AT. This mode reduces the need for the AT to indicate "Yes" (indicating that the designation was received) or "No" (indicating that the designation was not received). At 840, the unsubscribe message can be provided to request termination of the resend message to the AT. Similarly, at 850, the resend designation can be stopped.
圖9為併入有執行本發明之各種態樣之複數個模組之裝置。術語模組可指電腦相關實體，硬體、硬體與軟體之組合、軟體，或執行軟體，及電機械組件。舉例而言，模組可為(但不限於)在處理器上執行之方法、處理器、物件、可執行碼、執行緒、程式及電腦。藉由說明，在伺服器上執行之程序及/或伺服器可為模組。此外，模組可包括一或多個子組件。此外，熟習此項技術者應瞭解，創新方法可用其他電腦系統組態實施，包括單處理器或多處理器電腦系統、小型電腦、大型電腦、個人電腦、手持計算器件、基於微處理器及/或可程式化消費型電子元件，及其類似物，每一組件可操作以與一或多個相關聯器件通信。如圖9中所說明，裝置900可包括經由存取節點(AN)接收請求之模組910。接著，用於發送指定至AT之模組920可因此將指定提供至該AT。應瞭解，獨立模組960亦可在反向鏈路上提供該指定。隨後，實質上，經由用於重新發送指定至AT之模組930，可重新發送完全相同指定至AT。在初次嘗試之後，模組930亦可立即重新發送通道指定。解除指定訊息模組940可發送解除指定訊息，且(例如)請求終止重新發送訊息至AT。同樣的，用於停止重新發送指定之模組950可停止重新發送指定模組。用於選擇資源之模組980可選擇資源，其中一旦達到預定次數之重新發送嘗試，則可因此經由該模組980選擇另一資源。此外，例如，模組985可在反向鏈路上授權通道指定/固著(當存取節點("AN")未將該指定解碼時)。此外，模組995可推斷各個使用者通常何時應解除指定。此外，模組997可判定AN是否將指定解碼。Figure 9 is a device incorporating a plurality of modules for performing various aspects of the present invention. The term module can refer to a computer-related entity, a combination of hardware, hardware and software, software, or executive software, and electromechanical components. For example, a module can be, but is not limited to being, a method, a processor, an object, an executable, a thread, a program, and a computer executed on a processor. By way of illustration, the program and/or server executing on the server can be a module. Additionally, a module can include one or more sub-components. In addition, those skilled in the art should be aware that innovative methods can be implemented with other computer systems, including single or multi-processor computer systems, small computers, large computers, personal computers, handheld computing devices, microprocessor-based and/or Or programmable consumer electronic components, and the like, each component being operative to communicate with one or more associated devices. As illustrated in Figure 9, device 900 can include a module 910 that receives a request via an access node (AN). Next, the module 920 for transmitting the designation to the AT can thus provide the designation to the AT. It should be appreciated that the standalone module 960 can also provide this designation on the reverse link. Subsequently, essentially, via the means for resending the module 930 assigned to the AT, the exact same assignment to the AT can be resent. Module 930 may also resend the channel designation immediately after the initial attempt. The de-assignment message module 940 can send a de-assertion message and, for example, request to terminate resending the message to the AT. Similarly, the module 950 for stopping resending can stop resending the specified module. The module 980 for selecting resources may select a resource, wherein once a predetermined number of resend attempts are reached, another resource may be selected via the module 980. Further, for example, module 985 can authorize channel assignment/fixing on the reverse link (when the access node ("AN") does not decode the designation). In addition, module 995 can infer when each user should normally de-assign. Additionally, module 997 can determine if the AN will specify the decoding.
如先前所解釋之情況，未能將指定解碼通常不明確表示，解碼是否丟失，或存取終端機(AT)是否業已丟失指定；且因此本發明之一實施例立即經由模組930提供重新發送指定。該方式降低對AT指示"是"(表示接收到指定)或"否"(表示未接收到指定)之需求。因此，若AN未將指定解碼，則重新發送該指定(例如，一旦AN未能將指定解碼，則立即重新發送指定)，且可因此移除請求等待時間。As previously explained, failure to specify the decoding is usually not explicitly indicated, whether the decoding is lost, or whether the access terminal (AT) has lost the designation; and thus an embodiment of the present invention immediately provides retransmission via module 930. Specified. This mode reduces the need for the AT to indicate "Yes" (indicating that the designation was received) or "No" (indicating that the designation was not received). Thus, if the AN does not decode the designation, the designation is resent (eg, once the AN fails to decode the designation, the designation is resent immediately), and the request latency can therefore be removed.

For simplicity, the wireless communication system 1100 describes an access point and a terminal. However, it should be appreciated that the system can include more than one access point and/or more than one terminal, wherein the additional access points and/or terminals can be substantially similar or different than the exemplary access points and terminals described below. . In addition, it should be appreciated that access points and/or terminals can use the systems and/or methods described herein to facilitate wireless communication therebetween.
如圖11所說明，在下行鏈路上，存取點1105處，傳輸(TX)資料處理器1110接收、格式化、編碼、交錯及調變(或符號映射)訊務資料，且提供調變符號("資料符號")。符號調變器1115接收及處理資料符號及導頻符號，且提供符號流。符號調變器1115對資料及導頻符號進行多工處理，且將其提供至傳輸器單元(TMTR)1120。每一傳輸符號可為資料符號、導頻符號，或零訊號值。可在每一符號週期中連續發送導頻符號。導頻符號可經分頻多工(FDM)、正交分頻多工(OFDM)、分時多工(TDM)、分頻多工(FDM)，或分碼多工(CDM)。As illustrated in FIG. 11, on the downlink, at access point 1105, a transmit (TX) data processor 1110 receives, formats, encodes, interleaves, and modulates (or symbol maps) the traffic data and provides modulation symbols. ("data symbol"). The symbol modulator 1115 receives and processes the data symbols and pilot symbols and provides a stream of symbols. The symbol modulator 1115 performs multiplex processing on the data and pilot symbols and provides them to the transmitter unit (TMTR) 1120. Each transmission symbol can be a data symbol, a pilot symbol, or a zero signal value. The pilot symbols can be transmitted continuously in each symbol period. The pilot symbols can be divided by frequency division multiplexing (FDM), orthogonal frequency division multiplexing (OFDM), time division multiplexing (TDM), frequency division multiplexing (FDM), or code division multiplexing (CDM).
TMTR 1120接收符號流且將其轉換成一或多個類比訊號，且進一步調節(例如，放大、濾波及增頻變換)類比訊號以產生適合在無線通道上傳輸之下行鏈路訊號。下行鏈路訊號因此經由天線1125傳輸至終端機。在終端機1130處，天線1135接收下行鏈路訊號，且將已接收訊號提供至接收器單元(RCVR)1140。接收器單元1140調節(例如，放大、濾波及減頻變換)已接收訊號，且將經調節訊號數位化以獲取樣本。符號解調變器1145解調變已接收導頻符號且將其提供至處理器1150以進行通道估計。符號解調變器1145進一步自處理器1150接收用於下行鏈路之頻率響應估計，對已接收資料符號執行資料解調變以獲取資料符號估計(其為已傳輸資料符號之估計)，且將資料符號估計提供至RX資料處理器1155，其將資料符號估計解調變(例如，符號解映射)、解交錯及解碼以恢復傳輸訊務資料。由符號解調變器1145及RX資料處理器1155進行之處理補充在存取點1105處分別由符號調變器1115及TX資料處理器1110進行之處理。The TMTR 1120 receives the symbol stream and converts it into one or more analog signals, and further conditions (e.g., amplifies, filters, and upconverts) the analog signal to produce a downlink signal suitable for transmission on the wireless channel. The downlink signal is therefore transmitted to the terminal via antenna 1125. At terminal 1130, antenna 1135 receives the downlink signal and provides the received signal to receiver unit (RCVR) 1140. Receiver unit 1140 conditions (eg, amplifies, filters, and downconverts) the received signals and digitizes the conditioned signals to obtain samples. The symbol demodulator 1145 demodulates the received pilot symbols and provides them to the processor 1150 for channel estimation. The symbol demodulator 1145 further receives a frequency response estimate for the downlink from the processor 1150, performs data demodulation on the received data symbols to obtain a data symbol estimate (which is an estimate of the transmitted data symbols), and The data symbol estimates are provided to RX data processor 1155, which demodulates (e.g., symbol demaps), deinterleaves, and decodes the data symbol estimates to recover the transmitted traffic data. The processing by symbol demodulation transformer 1145 and RX data processor 1155 supplements the processing performed by symbol modulator 1115 and TX data processor 1110 at access point 1105, respectively.
在上行鏈路上，TX資料處理器1160處理訊務資料及提供資料符號。符號調變器1165接收並對資料符號及導頻符號並對其進行多工處理，執行調變，且提供符號流。傳輸器單元1170因此接收及處理符號流以產生上行鏈路訊號，其由天線1135傳輸至存取點1105。On the uplink, TX data processor 1160 processes the traffic data and provides data symbols. The symbol modulator 1165 receives and multiplexes the data symbols and pilot symbols, performs modulation, and provides a stream of symbols. Transmitter unit 1170 thus receives and processes the symbol stream to generate an uplink signal, which is transmitted by antenna 1135 to access point 1105.
在存取點1105處，來自終端機1130之上行鏈路訊號由天線1125接收且由接收器單元1175處理以獲取樣本。符號解調變器1180接著處理樣本，且提供用於上行鏈路之已接收導頻符號及資料符號估計。RX資料處理器1185處理資料符號估計以恢復由終端機1130傳輸之訊務資料。處理器1190執行在上行鏈路上之每一主動終端機傳輸之通道估計。在其個別指定之導頻子頻帶組上，多個終端機可在上行鏈路上同時傳輸導頻訊號，其中導頻子頻帶組可交錯。At access point 1105, the uplink signal from terminal set 1130 is received by antenna 1125 and processed by receiver unit 1175 to acquire samples. The symbol demodulator 1180 then processes the samples and provides received pilot symbols and data symbol estimates for the uplink. The RX data processor 1185 processes the data symbol estimates to recover the traffic data transmitted by the terminal 1130. Processor 1190 performs channel estimation for each active terminal transmission on the uplink. On its individually assigned set of pilot subbands, multiple terminals can simultaneously transmit pilot signals on the uplink, where the pilot subband groups can be interleaved.
處理器1190及1150分別在存取點1105及終端機1130處引導(例如，控制，協調，管理等等)操作。個別處理器1190及1150可與儲存程式碼及資料之記憶體單元(未展示)相關聯。處理器1190及1150亦可執行計算以分別得出用於上行鏈路及下行鏈路之頻率及脈衝響應估計。Processors 1190 and 1150 direct (e.g., control, coordinate, manage, etc.) operations at access point 1105 and terminal 1130, respectively. Individual processors 1190 and 1150 can be associated with a memory unit (not shown) that stores code and data. Processors 1190 and 1150 can also perform computations to derive frequency and impulse response estimates for the uplink and downlink, respectively.
對於多存取系統(例如，FDMA、OFDMA、CDMA、TDMA等等)，多個終端機可在上行鏈路上同時傳輸。對於該系統，導頻子頻帶可在不同終端機之間共用。在用於每一終端機之導頻子頻帶佔據整個操作頻帶(可能除頻帶邊緣外)情況下，可使用通道估計技術。該導頻子頻帶結構適合來獲取用於每一終端機之頻率分集。本文所說明之技術可以各種構件實施。舉例而言，此等技術可在硬體、韌體、軟體或其組合中實施。對於硬體實施，用於通道估計之處理單元可在一或多個特殊應用積體電路(ASIC)、數位訊號處理器(DSP)、數位訊號處理器件(DSPD)、可程式化邏輯器件(PLD)、場可程式化閘陣列(FPGA)、處理器、控制器、微控制器、微處理器、經設計以執行本文所說明功能之其他電子單元，或其組合內實施。對於軟體，可經由執行本文所說明功能之模組(例如，程序、函式，等等)實施。軟體碼可儲存在記憶體單元中，且由處理器1190及1150執行。For multiple access systems (eg, FDMA, OFDMA, CDMA, TDMA, etc.), multiple terminals can transmit simultaneously on the uplink. For this system, the pilot subbands can be shared between different terminals. Channel estimation techniques may be used where the pilot subband for each terminal occupies the entire operating band (possibly except for the band edges). The pilot subband structure is suitable for obtaining frequency diversity for each terminal. The techniques described herein can be implemented in a variety of components.
